D. green ppt .

Explanation

To solve the question, we need to analyze the reaction between aqueous copper sulfate (CuSO4) and aqueous ammonium hydroxide (NH4OH). Let's break down the steps:

### Step 1: Identify the Reactants
The reactants in this reaction are:
- Aqueous copper sulfate (CuSO4)
- Aqueous ammonium hydroxide (NH4OH)

### Step 2: Write the Chemical Equation
When copper sulfate reacts with ammonium hydroxide, the following reaction occurs:
\[ \text{CuSO}_4 (aq) + 2 \text{NH}_4\text{OH} (aq) \rightarrow \text{Cu(OH)}_2 (s) + \text{(NH}_4\text{)}_2\text{SO}_4 (aq) \]

### Step 3: Identify the Products
The products of this reaction are:
1. Copper hydroxide (Cu(OH)2), which precipitates out of the solution as a blue solid (pale blue precipitate).
2. Ammonium sulfate ((NH4)2SO4), which remains in the aqueous solution.

### Step 4: Describe the Precipitate
The copper hydroxide that forms is a blue precipitate. This is an important observation in the reaction.

### Step 5: Conclusion
The reaction of aqueous copper sulfate with aqueous ammonium hydroxide produces:
- A pale blue precipitate of copper hydroxide (Cu(OH)2)
- Aqueous ammonium sulfate ((NH4)2SO4)

### Final Answer
The products of the reaction are:
- Pale blue precipitate of copper hydroxide (Cu(OH)2)
- Aqueous ammonium sulfate ((NH4)2SO4)
